Nortel Networks 8600 manual ERS-86065#config snmp-v3 community info

Technical Configuration Guide for SNMP v2.0 December 2006

3.3.4 Modifying and/or adding community strings

Initially, there are 4 communities: first, second, index1 and index2. first represents the default read-only access (public) and second represents the default read-write access (private) created by the SNMPv3 engine. The access rights are determined by the Security Name from the VACM table.

Previously existing default communities prior to software upgrade to release 3.7 appear as index1 (private) and index2 (public). They can be modified or deleted. If you had other communities defined, they will appear converted as index3, index4, etc…

You can modify or delete those, but you can not delete the default communities first and second, however, you can change the community strings for them.

To change the default communities, for example, the index named first with a new community name of readonly and the index named second with a new community name of readwrite, enter the following commands:

•ERS-8606:5#config snmp-v3 community commname first new-commname readonly

•ERS-8606:5#config snmp-v3 community commname second new-commname readwrite

You will now not be able to access the switch with the default communities public and private; you will need to use readonly and readwrite instead.

Note: You will not be able to see those new communities as they are now encrypted and hidden. However, you can still always modify them.

If you wish to change or create further communities, alter the existing communities, create a new community or delete a community (for example, in case you have forgotten the community string, which is now encrypted and hidden).
